The goal of this project is to interpolate the z-values for the ball from the NGS-Highlight tracking data that is available. The following is an example of the usage:

First we get the NGS highlight data using the NGS highlights library (https://github.com/asonty/ngs_highlights)

source_url("https://raw.githubusercontent.com/asonty/ngs_highlights/master/utils/scripts/data_utils.R")
source_url("https://raw.githubusercontent.com/asonty/ngs_highlights/master/utils/scripts/plot_utils.R")
play_data <- fetch_play_data(playKey_ = 248)

Then we can call the add_z() function to add the z axis to a given play.

added_z <- add_z_to_play(play_data)

Then we can plot the given play in two formsthree_d_animate() or three_d_animate_static(). three_d_animate() gives us an animated frame by frame visualization of the results, and three_d_animate_static() gives us a static image with all of the paths rendered at once.

fig <- three_d_animate(added_z)
fig
fig <- three_d_animate_static(added_z)
fig
